Problem with nginx test

lol :D i didn't notice that :) , thanks steve for that
now i running the test came with
root at server [/]# /usr/local/nginx/sbin/nginx -t
: duplicate MIME type "text/html" in /usr/local/nginx/conf/nginx.conf:29
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
configuration file /usr/local/nginx/conf/nginx.conf test is successful
what is duplicate in the config ?
thanks
